Alongside the introduction of the current Apple TV design in fall 2010, Apple launched AirPlay. In short, AirPlay allows a user to watch a movie, listen to a song, or view a photo on an iPhone, iPad, iPod touch (or Mac in some cases) and stream that content to the Apple TV. AirPlay typically works well and we have even considered it a major innovation in the living room appliances space. Apple has continued to enhance AirPlay over the past few years, allowing the service to integrate with iTunes in the Cloud and function without a WiFi connection.
With OS X Yosemite and iOS 8, Apple has taken the AirPlay idea to new levels. This fall, as Apple previewed at WWDC earlier this month, a user can begin writing an email, viewing a webpage, or sending a text message on one Apple device, and then walk up to a different Apple product and continue that action. This feature is called Handoff and is part of a new suite of features called Continuity. Unlike AirPlay, a click to stream the content is not necessary.
